ENGINE-VALVE PACKING.

Application filed December To all whom it may concern: Be it known that I, ALFRED MoLsrAn, cit1- zen of the United States, residing at Lawton,

in the county of Woodbury and State of Iowa, have invented certain new and useful Improvements in an Engme-ValvePackmg,

of whichthe following is a specification.

My invention relatesto new and useful improvements in anengine and more particularly to a'packing adapted to be used in connection with an engineihaving a rotary valve.

The principal object of the invention resides in providing a packing, carried in the cylinder head, that is adapted to engage and form a tight joint around the rotary valve.

Another object of the inventlon consists in providing the cylinder head with a pocket 1 lowing specification and drawings which 1 Figure 1 is a longitudinal vertical sectioin Fig. 2 is a transverse vertical section, and

Fig. 3 is a detailed perspective of the packin members.

11 the drawings the numeral. 1 indicates the engine cylinder having the usual head 2 formed integral therewith and provided with.

a passage 3 therethrough. A valve casing 4 is formed on top of the cylinder head and has Th s a rotatable valve 5 mounted therein. rotatable valve is provided with the inlet port 6 and the exhaust port 7 as more par-- ticularl ings. for the reception of lubrlcatlng oil.

illustrated in Fig. 2 of the draw- A circular recess or pocket 9 is formed,

around the opening or passage 3 and -is adapted to receive my improved packing which is adapted to engage the rotatable valve and prevent leakage therearound. The packing is formed of two members indicated rooves 8 are formed in the valve Specification of Letters Patent. Pate ted D 28 1920 A 6, 1919. Serialpiio. 342,898.

at 10 and 11 and'the member 10 is interiorly beveled'tofformthe female member whereas the member lljiscexteriorly beveled to, form member 11 is indicated at 13. The member is formed of aplurality of sections cut as indicated more particularly in F ig. 3 of the "drawings and adapted to be assembled to fit into the pocket or recess 9. The member 11 ls concaved at the top as indicated at 14 so asto' conform: to the curvature of the -outer face of'the valve 5. A spring 15 is adapted the male member. The bevelof the member 10 1s indicated at 12 whereas the bevel of the to be receivedin the bottom of the recess or 7 pocket 9 iandcbears against the 'underface of thepacking member 10 so as to normally force the packing upwardly to form a tight.

fit around-the valve.

thought that my construction will be clearly understood as well as the advantages there I '70 F rom thefabove detailed description it is of. While my packing is primarily adapted A for internal combustionengines it. willbe understood thatitmight equally 'as well be.

' used in connection witha steam engine. By

providing the-packing in the cylinder head, 1 l A A engaging the rotatable valve,,a tight joint":

is provided and prevents the leakage ofgas or steam around the valve. be assembled in the position illustrated in the outer faceof the valve. The spring. 15 I will normally hold the packing up so as to tightly engage'the valve. I The foregoing description'and the drawings have reference to what may be considinvention. It is to be understood that I make such changes in construction and ar rangement and combinationof parts, materials, dimensions, etc. as' may prove expedient and fall pended claim.

. -Having thus Letters Patent is A Incombination with an engine cylinder The parts will ered the preferred, or approved, form of my within the scope of the ape Figs. 1*and 2 of the drawings the concaved portions 14.- of the male member 11 engaging fully described my invention what I claim as new and desire to secure by formed around thepassage, a rotatable valve mounted over'the passage,fa packing received in the recess and adapted to engage the valve,

7 having a passage in the, top'and afrecess said packing comprising a sectional interiorly tapered female member and exteriorly tapered male member, and a spring adapted to be received in the recess and engaging the under surface of the female member for forcing the male member into contact with the Valve.
